This invention relates to the art of dispensers and particularly to astructure for dispensing paste Vor cream-like substances fromcollapsible containers such as shaving soaps, tooth paste, librarypast/e, and the lih y lt is a primary object of my invention to providemeans for positively ejecting a lixed amount of the material to bedispensed (herel@ inat'ter designated as soap as one particular medium)at each of a series of succeeding like operations from a collapsibleunit until the unit is emptied.

An important object is to provide a dispensing structure adapted toreceive a collapsible filler unit and adapted to be opel'- ated to-pressthe contents from the unit in successive operations and to close theunit from the air between operations.

An important object resides in the means for initially shearing oil' theclosed discharg ing end of the 'collapsible unit.

Still further objects reside in the means for engaging the collapsibleunit and compressing thewalls together; in the means for operating thecompressing means from a lateral travel of a member pushed from without;and in providing for a uniform discharge from the unit at variousproportions of collapse of the unit.

These and other objects will become apparent in the followingdescription of my invention, with reference being made to theaccompanying drawings, in which Fig. 1 is a fragmentary front elevationof a dispenser embodying my invention;

Like characters ot reference indicate like parts throughout the severalviews in the drawings.

Referring iirst to Figs. 1-4 in the drawings, l form a box 15 open fromthe front with a supporting bracket 16 at the rear. Along the innerright hand side, I mount a bar 14' to be pivotally supported by the side@if by the top and bottom links 18 and 19 respect-ively so that the barnormally tends to drop longitudinally toward the box bottom with abodily movement toward the rear. A cover 2() is hinged at the top or'the bon 15 79 to swing down over the front of the box and have its sidesand lower end 21 telescope over the box and an arm 22 extends forwardlyfrom the bar 17 to be contacted by the inner side of the cover. This arm22 may be moved 7@ along the bar 17 to be secured thereto at any oint bythe set screw 78 through the flanffe $9. The barv 17 is normally heldupwardly and outwardly by a spring, here shown as the tension spring 23,which spring not onl 30 swings the bar 17 outwardly from the ba of thebox 15, but also, through the arm 22, swings the cover 20 outwardly.

1n the lower end of the box 15 is provided a boss 24 having a taperedhole vertically ex- 85 tending therethrough and the under side of thebox end is arcuate with its center of curvature at the hinge of the boxcover. The lid end is also arcuate to slide over the under side of thebox end with a close sliding t and 99 has a rearwardly projecting plate25 with a shearing edge at its rear side. An elongated hole 26 yisprovided in the plate 25 at the proper location whereby when the lid isin its normal outward position, the plate covers over the discharge endof the hole in the boss 24 with the elongated hole 26 forwardly thereof.

A collapsible container 27, here shown as the well known tube commonlyemployed to contain shaving cream, has a conical nipple 28 which isfitted into the hole through the boss 24 and is of sufficient length toproject on through below the box end as indicated by the dash lines,Fig. 2, the nipple being hollow but closed over its end. An annularshoulder 29 is provided about the nipple above the boss over whichshoulder a latch bar 30 pivoted on the boss 24 is swung to preventwithdrawal of the nipple from the hole in the boss. In this position thecontainer extends -vertically upward within the box 15 in an invertedposition. The lid or cover 2() is swung away from the opening in the boxduring the positioning of the container in the box as above described.

I provide a carriage 31 to have its back adapted to'slide verticallyover the inner side of the back wall of the box 15 and under the guidestrip 80. Side plates 32 and 33 extend forwardly from the back androtatably support a shaft 34 which is provided with a longitudinal slot35 therethrough, Fig. 10, to receive the upper Hattened end ofthecontainer whereby, by revolving the shaft 34, the container may be woundaround the shaft to compress the container walls together to form a flatribbon of double thickness. On the outer face of the plate 33 vis anlarm 36 pivoted by its lower end to the plate, having the shaft 34extending through a slot 37 there` in, and extending above the shaft tocarry a pawl`38 on its outer side. A ratchet wheel 39 is fixed on theouter end of the shaft 34 to have the arm 36 between it and the plate33. A leg 40 extends rearwardly from the arm 36 and has an outwardlyturned finger 41 positioned to pass transversely across the back edge ofthe bar 17 whereby rearward travel of the bar 17 will push on the nger41 to cause the pawl 38 to engage the teeth of the wheel 39 and therebyrevolve the shaft 34. To limit the rotation of the wheel, an adj ustablestop 42 is carried on the plate 33 to contact the under side of the pawl38 to hold it away from engagement with teeth of the Wheel as may bedesired, lowering the stop causing the pawl to engage the wheel morequickly than when raised.

I The container 27 having been positioned in the box and the shaft 34engaged over the upper end of the container,.the cover 2O is swungaround to close 'the box 15 and the shearing edge of the plate 25 comesinto contact with the end ofthe nipple 28 projecting through the bottomof the box. The cover is pushed back to cause the nipple end to besheared off' and to cause a spring finger 43 to slide up over a stop 44on the box end and drop down therebehind with its downturned end topreventbutward travel of the cover. By pushing the cover on in furtherover the box, the arm 22 is pushed to move the bar 17 rearwardly whichcarries the arm 36 rearwardly to have the pawl 38 revolve the wheel`revolving means.

39 and thus wind `the container 27 around the shaft 34 a short distancewhereupon the pressure thus exerted on the contents of the containercauses the contents to flow out the opened end of the nipple 28, theplate 25 having moved in to have the hole 26 register over the nippleend. Release of the cover permits the spring 23 to return the parts totheir normal position ready for a subsequent operation, the nipple endbeing then closed over by the plate 25 to exclude air therefrom and toprevent further exudation of the contents.

As the container 27 is wrapped around the shaft 34 in a collapsedcondition, uniform rotation of the shaft 34 at each operation of thecover 20 would .cause an increasing amount of discharge therefrom due tothe increasing diameter of thecollapsed tube on the shaft. To compensatefor this condition, I slope the rear edge of the bar 17 to have itslower end closer to the back of the box 15 than is its top so that asthe carriage 31 drops downwardly with the emptying of the container, thearm 36 is not permitted to return as far forwardly as at the upperpositions and hence the pawl 38 can not engage the ratchet wheel to moveit as far. When the container'27 is emptied, a rod 45, shown in dashlines, Fig. 2, may be inserted through a hole 46 in the bottom of thebox 15 to raise the spring 43 above the stop 44 and thereby permit thecover to be pulled out from over the box and opened around to permit thelatch bar 30 to be moved from over the shoulder 29 so that the container27 may be lifted up to withdraw the nipple from the boss. By pulling onthev lower end of the container it may be readily unwound from the shaft34, disengaged therefrom, and a new filled container substitutedtherefor.

Asa precaution to prevent damage to the mechanism by further operationof the cover when the container is empty, l provide a stop post 47 onthe side of the box 15 to project into the path of the outer end of thepawl 38 at the proper elevation to contact the pawl and hold it up outof engagement with the. wheel 39 when the container is emptied therebypreventing further rotation of the shaft 34.

In Fig. 11, is shown a slightlv modified Here the carriage 31 isreversed and the wheel 39 is on the'let hand side with an arm 48 pivotedon the shaft 34 to have an extension 49 over to the operating bar 17 toreceive rocking motion therefrom as before. The lower end of the arm 48extends below the wheel 39 to carry a pawl 50 thereon having a weightedouter arm to cause the pawl to swing upwardly against' the wheel. Aspring 51 insures contact of the pawl with the wheel, and a spring 52engaging this lower end of the arm 48 normally rocks the arm to maintainthe extension finger 53 against the bar 17. Therefore,

Lacanau when the bar 17 is moved rearwardly, the fin er 53 is carriedback to rock the arm 48 an cause the pawl to revolve the wheel 39. A dog54 pivoted on the plate 33 drops cover 56 is used. A carriage 57 isslidably carried in the box and rotatabl supports the shaft 58comparable to the sha t 34. A shaft 59 is rotatably carried in the boxand has a bevel gear 60 carried thereon in driving relation by engaginginthe keyway 61 and is slidable therealong. The gear v60 is in constantmesh with the gear 62 lixed on the shaft 58. A plunger 63 extendsthrough the cover 56 and is normally extended by a spring 64 to have thestop 65 on the plunger contact the inner side of the cover as a limitingelement. On the side of the plunger 63 are formed teeth in the nature ofa rack bar which are inconstant mesh with a ring gear 66 rotatablysupported around the star member 67 which is fixed on the vertical shaft59. The star member 67 is provided with a plurality of right anglednotches 68, here shown as four in number, one side of the notch being ona radius with the other side at right angles thereto. In each notch, ispositioned a ball bearing 69 having a diameter slightly less than thelength of the radial side of the notch and a spring 70 urges eachball'out- Wardl into the acute angle formed between the ot er side ofthe notch and the inner face of the ring gear 66. Now as shown in Fig.8, pushing in on the plunger 63 will revolve the gear 66, and since theballs 69 are in contact therewith, they will be wedged between the gearand the sides of the notches of the star member 67 and thereby revolvethe mem- 1 ber 67 and the shaft 59 to, in turn, revolve the shaft 58upon which the collapsible unit is wound. In this modified form, theunder side of the vbox 55 is provided with a widened T-slot in which avalve plate 71 slides to close off the nipple end of the container 27. Anotch is provided through the box above the plate and a neck 72 connectsthe plate with the plunger 63 whereby the plunger moves the plate uponactuating the shaft 58.

Referring to Figs. 5 and 6, it is ossible to actuate the bar 17 by aplunger rod 73 in place of a hinged cover as shown in Fig. 1 4. `The rod73 is slidingly carried through the stationary cover 56 with aconnection 75 to the valve plate 76 on the under side of. the box and iscarried rearwardly to Contact the bar 17 so that by pushing in on therod 73, the bar 17 is moved rearwardly as above described. The plate 76is moved across the container nipple opening to open and close it andcarries a shearing edge on its backside for the initial shearing oli ofthe nipple end.
